hi there, I have a 1963 vnb vespa (see following post):

http://www.modernvespa.com/forum/topic34193?view=previous

and havnt done much with it, however I have a problem that I would like some advice on. it was starting well with a couple of kicks a couple of months ago, until it started to play up - I like to kick it over now and again just to blow the cobwebs out.

it was firing, running for about 3 seconds, then cutting out, and from there it wouldnt start again.

now - it doesnt start at all, regardless what I try.

I have had the plug out and cleaned it up, checked for a spark against the engine and all looks good.

I have taken the air filter off, and put a cap of fuel straight into the carb (just in case the fuel tap was a bit wonky), still nothing.

im not sure what to try next really, I would be happy if I got a single fire out of it at the moment, but it seems dead.

I intend to do a full resto on it, including an engine rebuild, but like I say, it would be nice just to get a fire out of it in the meantime to keep me happy

can anyone help me get this puppy running again

Also, try a little bit of ether enriched fuel that has a bit more "ignitability" Al

That's one approach. And then there's this: Which is a wee bit more accurate. Al

Spray can engine starter fluid, for example. Just a try or two, lest you create lube problems. Al
